AI Technical Summary
Technical Problem
[0003]传统的在安装夹具过程中，无法得知夹具对电芯的压力，压力过大易造成电芯变形，压力过低则达不到实验要求，影响实验结果，另外传统夹具多为实心夹具，温箱温感线只能粘贴电池未与夹具接触的四周面，对电芯整体温度无法做到准确测量，实心结构阻碍气流流通，也影响温箱对电芯的温度调节，为此我们提出一种电芯性能的测试夹具
Benefits of technology
[0023]本实用新型通过导流孔、连接凹槽及接口组件，便于与温箱连接，从而将原本分散的温控气流转化为集中穿透式高速气流，直接解决传统测试中换热慢、温场不均的问题，提高换热效率，且在对电芯夹紧时，能够通过压力传感器实时观察螺栓螺母拧入时，该处夹紧力对电芯的施压情况，便于及时进行调整，在电芯测试过程中，通过温度传感器能够实时对电芯中部温度进行检测，便于精准判断电芯整体温度情况，增大了装置的实用性，易于使用。
